Abstract
Cowpea weevil, Callosobruchus maculatus, is the primary pest of stored cowpea seeds. The management of this infestation currently relies on insecticides, resulting in environmental pollution and selection of insecticide-resistant pests. Consequently, research efforts are being devoted to identify natural insecticides as sustainable and environment friendly alternatives for the control of C. maculatus. In this study, we explore the toxic effects of the nonhost seeds Parkia multijuga, Copaifera langsdorffii, Ormosia arborea, Amburana cearensis, Lonchocarpus guilleminianus, Sapindus saponaria, and Myroxylon peruiferum, on the cowpea weevil C. maculatus. Notably, all nonhost seeds led to reductions between 60 and 100% in oviposition by C. maculatus females. Additionally, the larvae were unable to penetrate the nonhost seeds. Artificial seeds containing 0.05% to 10% of cotyledon flour were toxic to C. maculatus larvae. Approximately 40% of larvae that consumed seeds containing 0.05% of O. arborea failed to develop, in contrast to control larvae. Proteomic analysis of A. cearensis and O. arborea seeds identify revealed a total of 371 proteins. From those, 237 are present in both seeds, 91 were exclusive to O. arborea seeds, and 43 were specific to A. cearensis seeds. Some of these proteins are related to defense, such as proteins containing the cupin domain and 11S seed storage protein. The in silico docking of cupin domain-containing proteins and 11S storage protein with N-acetylglucosamine (NAG)4 showed negative values of affinity energy, indicating spontaneous binding. These results showed that nonhost seeds have natural insecticide compounds with potential to control C. maculatus infestation.

Bertonceli MAA, Oliveira AEA, Ferreira ATS, Perales J, Fernandes KVS. A vicilin-like protein extracted from Clitoria fairchildiana cotyledons was toxic to Callosobruchus maculatus (Coleoptera: Chrysomelidae). PESTICIDE BIOCHEMISTRY AND PHYSIOLOGY 2022; 184:105129. [PMID: 35715067 DOI: 10.1016/j.pestbp.2022.105129] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/23/2021] [Revised: 05/03/2022] [Accepted: 05/18/2022] [Indexed: 06/15/2023]
Abstract
Callosobruchus maculatus is the main pest cowpea (Vigna unguiculata). Given its relevance as an insect pest, studies have focused in finding toxic compounds which could prevent its predatory action towards the seeds. Clitoria fairchildiana is a native Amazon species, whose seeds are refractory to insect predation. This characteristic was the basis of our interest in evaluating the toxicity of its seed proteins to C. maculatus larvae. Seed proteins were fractioned, according to their solubility, to albumins (F1), globulins (F2), kaphyrins (F3), glutelins (F4), linked kaphyrins (F5) and cross-linked glutelins (F6). The fractionated proteins were quantified, analysed by tricine-SDS-PAGE and inserted into the diet of this insect pest in order to evaluate their insecticidal potential. The most toxic fraction to C. maculatus, the propanol soluble F3, was submitted to molecular exclusion chromatography and all of the peaks obtained, F3P1, F3P2, F3P3, caused a reduction of larval mass, especially F3P1, seen as a major ~12 kDa electrophoretic band. This protein was identified as a vicilin-like protein by mass spectrometry and BLAST analysis. The alignment of the Cfvic (C. fairchildiana vicilin) peptides with a V. unguiculata vicilin sequence, revealed that Cfvic has at least five peptides (ALLTLVNPDGR, AILTLVNPDGR, NFLAGGKDNV, ISDINSAMDR, NFLAGEK) which lined up with two chitin binding sites (ChBS). This finding was corroborated by chitin affinity chromatography and molecular docking of chitin-binding domains for N-Acetyl-D-glucosamine and by the reduction of Cfvic chitin affinity after chemical modification of its Lys residues. In conclusion, Cfvic is a 12 kDa vicilin-like protein, highly toxic to C. maculatus, acting as an insect toxin through its ability to bind to chitin structures present in the insect midgut.

Vicilin from Anadenanthera colubrina Seeds: An alternative tool to combat Callosobruchus maculatus. Saudi J Biol Sci 2021; 28:5229-5237. [PMID: 34466101 PMCID: PMC8381016 DOI: 10.1016/j.sjbs.2021.05.041] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2021] [Revised: 05/15/2021] [Accepted: 05/18/2021] [Indexed: 11/03/2022] Open
Abstract
Vicilins are seed proteins, and they constitute 70-80% of the total protein in leguminous seeds; with amolecular mass between 150 and 190 kDa, they are composed of subunits without disulfide bridges, with high affinity for chitin-binding. They are also associated with seed defense against insect pests. The chitin-binding vicilin from Anadenanthera colubrina seeds was purified by ammonium sulfate, followed by affinity chromatography on a chitin column, molecular exclusion on Superdex 75 Tricorn in FPLC system and Phenomenex C8 chromatography in HPLC system. The A. colubrina vicilin, named AcV, is a tetrameric glycoprotein composed of 1.55% carbohydrates and molecular weight determined by SDS-PAGE, consisting of 70, 73, 43 and 41 kDa. The AcV homogeneity was confirmed in native PAGE, where it was observed to be a unique band with slow mobility in this gel, with approximately 230 kDa. AcV added to the Callosobruchus maculatus diet in the bioassays resulted in a strong effect on adult emergence (ED50 of 0.096%), and in larvae caused a marked reduction in mass (WD50 of 0.32%) and lethality (LD50 of 0.33%) (w:w). The digestibility of AcV was evaluated in vitro with the digestive enzymes of larvae of C. maculatus of fourth instar, showing major fragments of 10 and 30 kDa. AcV showed reactivity against the anti-EvV antibody from Erythrina velutina vicilin. The deleterious effects of AcV are likely to be associated with the chitin-binding fragments generated by proteolysis in the bruchid gut, similarly to that found for vicilins from other leguminous plant species, Enterolobium contortisiliquum and Vigna unguiculata. AcV might be a candidate protein for a possible bioinsecticidal control of the bruchid weevil, C. maculatus.

Abstract
The cowpea weevil (Callosobruchus maculatus) is the main pest that attacks cowpea (Vigna unguiculata) seeds during storage, causing nutritional and economic losses in the cowpea crop. Thus, studies aiming to identify resistant cowpea cultivars have been developed. Chitin-binding proteins (CBP), such vicilins and chitinases, have been detected in seeds and related with the toxicity to insects. In this work, we investigated the presence of chitin-binding proteins in the partially resistant cowpea cv. BRS Xiquexique and evaluated their toxicity towards cowpea weevil. The CBP fraction was isolated by chitin affinity chromatography. CBP fraction showed, through 15% SDS PAGE, protein bands with varying molecular masses, mainly below 55 kDa. Proteins present in CBP fraction were identified by Western blotting and mass spectrometry analysis, as vicilins and chitinases. CBP fraction, at 5%, was able to interfere with the development of cowpea weevil, decreasing larval mass and length. A CBV (chitin-binding vicilin) fraction isolated from CBP fraction was toxic, at 2.0%, to C. maculatus, decreasing larval mass and length in 64.3% and 33.23%, respectively. These results suggest that chitin binding proteins, such vicilins and chitinases, may be related to the resistance of cowpea cv. BRS Xiquexique to the infestation by C. maculatus.

Abstract
Vicilins are related to cowpea seed resistance toward Callosobruchus maculatus due to their ability to bind to chitinous structures lining larval midgut. However, this binding mechanism is not fully understood. Here, we identified chitin binding sites and investigated how in vitro and in silico chemical modifications interfere with vicilin chitin binding and insect toxicity. In vitro assays showed that unmodified vicilin strongly binds to chitin matrices, mainly with acetylated chitin. Chemical modifications of specific amino acids (tryptophan, lysine, tyrosine), as well as glutaraldehyde cross-linking, decreased the evaluated parameters. In silico analyses identified at least one chitin binding site in vicilin monomer, the region between Arg208 and Lys216, which bears the sequence REGIRELMK and forms an α helix, exposed in the 3D structure. In silico modifications of Lys223 (acetylated at its terminal nitrogen) and Trp316 (iodinated to 7-iodine-L-tryptophan or oxidized to β-oxy-indolylalanine) decreased vicilin chitin binding affinity. Glucose, sucrose, and N-acetylglucosamine also interfered with vicilin chitin binding affinity.

Abstract
The objective of this study was to determine whether seeds of Brassica oleracea var. italica (i.e. broccoli, an edible plant) produce defensins that inhibit phytopathogenic fungi and pathogenic bacteria of clinical significance. Crude extracts obtained from broccoli seeds were fractioned by molecular exclusion techniques and analyzed by liquid chromatography-high-resolution mass spectrometry. Two peptides were identified, BraDef1 (10.68 kDa) and BraDef2 (9.9 kDa), which were categorized as Class I defensins based on (a) their primary structure, (b) the presence of four putative cysteine disulfide bridges, and (c) molecular modeling predictions. BraDef1 and BraDef2 show identities of, respectively, 98 and 71%, and 67 and 85%, with defensins from Brassica napus and Arabidopsis thaliana. BraDef (BraDef1 + BraDef2) disrupted membranes of Colletotrichum gloeosporioides and Alternaria alternata and also reduced hyphal growth of C. gloeosporioides by ~ 56% after 120 h of incubation. Pathogenic bacteria (Bacillus cereus 183, Listeria monocytogenes, Salmonella typhimurium, Pseudomonas aeruginosa, and Vibrio parahaemolitycus) were susceptible to BraDef, but probiotic bacteria such as Bifidobacterium animalis, Lactobacillus acidophilus, and Lactobacillus casei were not inhibited. To our knowledge, this is the first report of defensins present in seeds of B. oleracea var. italica (i.e. edible broccoli). Our findings suggest an applied value for BraDef1/BraDef2 in controlling phytopathogenic fungi and pathogenic bacteria of clinical significance.

Abstract
The seed coat is an external tissue that participates in defense against insects. In some nonhost seeds, including Albizia lebbeck, the insect Callosobruchus maculatus dies during seed coat penetration. We investigated the toxicity of A. lebbeck seed coat proteins to C. maculatus. A chitin-binding protein fraction was isolated from seed coat, and mass spectrometry showed similarity to a C1 cysteine protease. By ELM program an N-glycosylation interaction motif was identified in this protein, and by molecular docking the potential to interact with N-acetylglucosamine (NAG) was shown. The chitin-binding protein fraction was toxic to C. maculatus and was present in larval midgut and feces but not able to hydrolyze larval gut proteins. It did not interfere, though, with the intestinal cell permeability. These results indicate that the toxicity mechanism of this seed coat fraction may be related to its binding to chitin, present in the larvae gut, disturbing nutrient absorption.

Abstract
Seed coat is a specialized maternal tissue that interfaces the embryo and the external environment during embryogenesis, dormancy and germination. In addition, it is the first defensive barrier against penetration by pathogens and herbivores. Here we show that Albizia lebbeck seed coat dramatically compromises the oviposition, eclosion and development of the bruchid Callosobruchus maculatus. Dietary supplementation of bruchid larvae with A. lebbeck seed coat flour causes severe weight loss and reduces survival. By means of protein purification, mass spectrometry and bioinformatic analyses, we show that chitinbinding vicilins are the main source of A. lebbeck tegumental toxicity to C. maculatus. At concentrations as low as 0.1%, A. lebbeck vicilins reduce larval mass from 8.1 ± 1.7 (mass of control larvae) to 1.8 ± 0.5 mg, which corresponds to a decrease of 78%. Seed coat toxicity constitutes an efficient defense mechanism, hindering insect predation and preventing embryo damage. We hypothesize that A. lebbeck vicilins are good candidates for the genetic transformation of crop legumes to enhance resistance to bruchid predation.

Abstract
Legumin-like proteins from seeds of Coffea arabica (CaL-1 and CaL-2) and Coffea racemosa (CrL-1 and CrL-2) were characterized and isolated by gel filtration and reverse-phase chromatography. The insecticidal properties of the purified proteins were tested against Callosobruchus maculatus using artificial diets. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) analyses indicated that CaL-1 is composed of two subunits of 33 and 24 kDa, while CaL-2, CrL-1, and CrL-2 were monomeric with a single band of 14 kDa. The LD(50) values were 0.5% (w/w) for CaL-1 and 0.3% (w/w) for CaL-2, CrL-1, and CrL-2. ED(50) at 0.3% was assessed for all protein concentrations. The legumin-like proteins were not digested by midgut homogenates of C. maculatus until 8 h of incubation. CaL-1 and CaL-2 ( C. arabica ) and CrL-1 and CrL-2 ( C. racemosa ) are chitin-binding proteins, and their insecticidal properties toward C. maculatus larvae might be related to their capacity to bind chitin present in the larval gut and their associated low digestibility.
